VENTlLATlNG-SASH.

SPECIFICATION forming part of Letters Patent No. 429,796, dated June 10,1890.

Application filedNovemberZQ, 1889. Serial No. 332,061. (No model.)

T0 at whom it may concern.-

Be it known that I, JOHN PHILIPP RIEFFEL, of the city, county, and Stateof New York, a citizen of the United States, have invented certain newand useful Improvements in Ventilating-Sashes, of which the following isa specification.

This invention relates to improvements in that class of sashes that areknown as ventilating-sashes, and are usually provided in the upper partsof the walls for the purpose of ventilation.

The object of my invention is to provide a sash of this kind, and to soconstruct it that the water of condensation that collects on the panes,or the water that is driven in by the wind, is conducted off and cannotflow down on the inner surface of the wall.

The invention consists in the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, andfinally pointed out in the claim.

In the accompanying drawings, Figure 1 is an outside elevation of myimproved ventilating-sash. Fig. 2 is a side view of the same, showingthe sash open. Fig. 3 is an enlarged horizontal sectional view on theline 3 3, Fig. 1. Fig. 4is an enlarged detail cross-sectional View onthe line 4 4, Fig. 1. Fig. 5 is an enlarged detail cross-sectional viewon the line 5 5, Fig. 1. Fig. 6 is an outside elevation of a modifiedconstruction of the ventilating-sash. Figs. 7 and 8 are verticaltransverse sectional views on the lines 7 7 and 8 8,1espectively, Fig.6, parts of Figs. 6, 7, and 8 being broken out.

Similar letters of reference indicate corresponding parts.

In the construction shown in Figs. 1 to 5 the sash-frame is made ofmetal, the side pieces A, the bottom piece 13, and the top piece 0 beingprovided at the inner edges with inwardly-extending flanges A, B, and C,respectively. In the inner surface of the side pieces A the verticalgrooves D are formed, the lower ends of which are in communication withthe longitudinal groove E in the upper surface of the bottom piece B,said groove being in communication with the grooved spout G, projectingtoward the outside of the sash-frame. The interior and exterior flangesA, B, and C are provided with longitudinal grooves H in their innerfaces, into which grooves rubber packing-strips can be placed, so as toform a wind and water proof joint. The sash J is pivoted in thesash-frame slightly below the center of the sash, so that when the sashis released its upper part swings outward. The lower half of the sash isprovided on the inner side with a laterally-projecting flange K, in theinner surface of which the longitudinal groove K is formed, which alsoserves for carrying off water. The upper part or half of the sash isprovided on the outer surface with the flange L, which is also providedwith an internal longitudinal groove for carrying off water.

A cord M is secured to an eye or lug M on the bottom part of the sash,and a cord N is connected with the spring-bolt N, provided at the toppart of the sash, which spring-bolt can snap into asuitable catch N onthe top of the casing. The water of condensation, or the water that isdriven in from the outside, flows down through the grooves 0 into thegroove E and flows oif through the outwardlyproject-ing spout G, thuspreventing this water from flowing down on the inner surface of thewalls, as it would do if proper means were not provided for conductingit off.

0 is a stiffening-rod connecting the two side bars of the swinging sash.

In the construction shown in Figs. 6, 7, and 8 the sash is to be hingedat one side to swing inward, and is provided on the outside with adownwardly and outwardly inclined deflecting-plate R. The water thatflows down the panes is conducted outward by said defleeting-plate. Thebottom piece S of the window-casing is provided with a longitudinalgroove S, at the ends of which openings T are formed, through which thewater can flow off.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination, with a window-casing having groovesin the inner surfaces of its side pieces and a groove in the uppersurface of its bottom piece, said groove in the bottom piece having anoutlet-aperture, of In testimony that I claim the foregoing as flangesformed on parts of said casing, which my invention I have signed my namein presfianges have grooves for receiving pnckingence of two subscribingWitnesses.
